Research Report 151 Dynamic load properties of New Zealand basecourse

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

This report follows on from Opus Report 95-526264.01, which recommends a test procedure for New Zealand basecourse materials. The adoption of the Australian standard test is problematic because the proposed New Zealand test procedure is slightly different and New Zealand basecourses and conditions also differ from those in Australia.

This report compares the performance of three basecourse materials under a range of conditions using both the Australian Standard test and the proposed New Zealand test and recommends a test protocol that will distinguish between material that could be regarded as a premium basecourse and material whose performance could be suspect.

Keywords: basecourse, subgrade, aggregates, resilient mosulus, permanent strain
